ملخص المقالة :
The germination of pollen grains is the most important aspect in fertilization and fruit or seed/grain setting and yield. Hence the influence of pesticides on pollen germination is the key issue in improvement of crop yield. Pollen grains from the anthers of fully opened flowers of tomato and brinjal plants treated with different concentration of chloropyrifos and malathion along with control were freshly collected at morning and immediately brought to the laboratory. Pollen germi[1]nation was studied by using the method of Heslop-Harrison. The results showed that the percentage of inhibition of pollen germination in tomato was highly increased with increasing concentrations of chloropyrifos and malathion. But in brinjal the percent inhibition of pollen germination was not significant and mostly at par with control. The highest percentage inhibition of pollen germination in tomato treated with chloropyrifos was 67.08% and by malathion it was 73.19%. The inhibition of pollen germination in brinjal treated by chloropyrifos was 54.69% and by malathion it was 54.76%. The re[1]sults indicated that malathion had more adverse effect on pollen germination in tomato and brinjal as compared to chloro[1]pyrifos. The higher concentrations of pesticides affected the growth, development, yield as well as physiology, biochemi[1]stry and enzymology of treated plants
